Hi,

I agree with David's response.
Also want to add that a Content Data Object is a Data Object that hold the Content data.
It is NOT the content of a Data Object.  A Data Object could hold other types of data - Representation, Fixity, Context, etc.  In those cases that Data Object would NOT be a CDO.

Wishing you prosperity and peace,

My explanation:

OAIS defines Content Data Object as: The Data Object, that together with associated Representation Information, comprises the Content Information.

In other words, a "Data Object" is the general term. A "Content Data Object" is a specific Data Object, for example being preserved within an AIP.

Does that help?

Dear all,

During the translation of the OAIS in French, the following question has been raised : what is exactly the meaning of "Content Data Object" (is it an object representing the Content Data or the content of a Data Object ?) and what is its relation with "Data Object" ?
I hope some of you could help me to clarify these two concepts.

Thanks again.
